Filter by:The main objective of this study is to predict cartilage contact pressures in the hip after periacetabular osteotomy (PAO).
The purpose of this study is to examine the movement pattern in patients with hip dysplasia preoperative, six and 12 month after minimally invasive approach for Periacetabular osteotomy (PAO). Secondary to examine the movement pattern in patients compared to healthy controls and historical data.
The project runs as a Ph.d. project at the Faculty of Health Sciences- University of Copenhagen. In Denmark the investigators operate around 16.000 artificial hips and knees yearly, mainly due to osteoarthritis. The numbers has increased with 13,9% for hips and 50,7% for knees in the period 2004 to 2007. In 10% of the cases, or approximately 1.600 patients, the patient is younger than 50 years - mid-life, working, socially active and sexually active. The investigators have a tendency within in the orthopedic society to mainly focus on the technological aspects of the procedure and tend to forget that this is a key event for the patient with widespread consequences for the patient and his future life. Hip- and knee arthroplasties is without no doubt two of the most important and successfully surgical procedures ever introduced. The economical cost for osteoarthritis treatment has exploded in the developed world over the last decade, with a yearly growth on 8%. Because of the limited lifetime for an artificial hip or knee, this treatment can be unfortunate for the young patient. This has over the last years led to an increased interest for joint preserving surgery. Over the last twenty years it has been tried to delay the time for total hip arthroplasties for patients with hip dysplasia with the aid of Ganz osteotomy. Since this technique was introduced back in 1988, the research on the topic has had its main focus on optimizing the operation technique. So as with surgery with artificial hip or knee the investigators have a lack of knowledge regarding the social, work related, psychological and sexual aspects of this treatment. Purpose The consequences of an artificial hip or knee joint regarding patients' social-life, work, psychological and sexual aspects gain very little attention international. The investigators apply most of our research funds exclusively to research and development of the surgical track and procedure, new prosthesis designs or coatings. The investigators find this study highly relevant because this kind of studies has been preformed for several chronic diseases but not osteoarthritis and its treatment. With this study the investigators wish to examine the social, work related, psychological and sexual aspects of end stage osteoarthritis. This will lead the way for improved information to the patient and improve the surgeons' possibilities for chosen the correct time for surgery.
The primary objective of the study is to find the gene(s) responsible for causing DDH. The secondary objective of the study is to determine the mode of genetic transmission of DDH.
